背景：睡眠不足在青少年中很常见，并对健康和行为产生不良影响。了解身体活动和久坐行为与睡眠时间的关系，可以帮助我们找到促进充足睡眠的方法。目的：本研究的目的是确定美国高中生的体育活动和久坐行为是否与充足睡眠（平均每晚8小时或更长时间的睡眠）有关。方法：数据来自2009年全国青少年危险行为调查，具有全国9 -12年级学生的代表性（n=14,782）。使用控制混杂因素的逻辑回归模型确定体力活动和久坐行为与充足睡眠的关联。数据于2010年10月进行分析。结果：在调查前的7天内每天进行>= 60分钟体育锻炼的学生比那些每天都没有进行>= 60分钟体育锻炼的学生有更高的机会获得充足的睡眠。学生进行20分钟剧烈运动的天数与充足的睡眠之间没有关联。与每天平均上学时间为0小时的参照组相比，每天看电视4小时的学生睡眠充足的几率更高，而每天玩视频或电脑游戏或使用电脑做非学校工作2小时的学生睡眠充足的几率更低。结论：青少年每天运动60分钟和有限的电脑使用与充足的睡眠有关。（Am J Prev Med 2011;41(6):596-602） Elsevier Inc.代理美国预防医学杂志出版
Background: Insufficient sleep among adolescents is common and has adverse health and behavior consequences. Understanding associations of physical activity and sedentary behaviors with sleep duration could shed light on ways to promote sufficient sleep.Purpose: The purpose of this study is to determine whether physical activity and sedentary behaviors are associated with sufficient sleep (8 or more hours of sleep on an average school night) among U. S. high school students.Methods: Data were from the 2009 national Youth Risk Behavior Survey and are representative of 9th-12th-grade students nationally (n=14,782). Associations of physical activity and sedentary behaviors with sufficient sleep were determined using logistic regression models controlling for confounders. Data were analyzed in October 2010.Results: Students who engaged in >= 60 minutes of physical activity daily during the 7 days before the survey had higher odds of sufficient sleep than those who did not engage in >= 60 minutes on any day. There was no association between the number of days students were vigorously active >= 20 minutes and sufficient sleep. Compared to their respective referent groups of 0 hours on an average school day, students who watched TV >= 4 hours/day had higher odds of sufficient sleep and students who played video or computer games or used a computer for something that was not school work >2 hours/day had lower odds of sufficient sleep.Conclusions: Daily physical activity for >= 60 minutes and limited computer use are associated with sufficient sleep among adolescents.
